Perhaps it's supposed to mean just what the C Standard
says it means:  that 'f' is a character array;  that
the character array 'f' is defined in this translation
unit;  that the array could be given a specific size
in a later declaration, or later definition;  and that,
if not given a specific size explicitly (perhaps as a
consequence of a subsequent definition including an
initializer), it will be defined implicitly as having
one element, initialized using the value zero.
